Usage Notes & Package

Critical Notes:

Requires a robust 28V / 6A (minimum) DC power supply for full performance.
Mandatory active cooling (e.g., substantial heatsink with radiator fan) is required for safe, sustained operation during long flights.
Safety Connection Sequence: Always connect the antenna first, then apply power, and finally enable your video transmitter or control source.
Output can reach up to 49dBm with adequate input drive and cooling.

Package Includes: 1 x Ultra-High-Power Amplifier Unit.
